ABSTRACT:
A method of manufacturing a solid preparation coated with a non-solvent coating which is prepared by feeding a polymeric powder directly as coating agent while continuously spraying a solid medicine with an atomized mixture of a liquid substance, which has a contact angle against the polymer coating agent of 10 degrees or less, and a plasticizer. A method of manufacturing a dry-coated solid preparation in which a solid preparation, coated with a non-solvent coating, is treated by adding or spraying an atomized water or an aqueous solution of a water soluble substance in the amount of 1-10 wt % of the solid preparation to wet said "coating layer" followed by drying.
